Malabar Cogeneration Facility

Location: Malabar, NSW

Use / Host

Heat is recovered from a hot water heat exchanger. The waste heat is used for heating raw sewage sludge feed to digesters. Digested sludge is de-watered and used for agricultural biosolids.

Energy Purchase and Supply

Digester gas is combusted in the engines and heat recovered from the cogeneration facility is used to heat raw sewage sludge before going to the digester.

The electricity produced is treated as "green power" under a scheme accredited by the Sustainable Energy Development Authority of New South Wales and is consumed onsite for the sewage treatment plant.

The plant operates in base-load mode subject to the availability of digester gas.

Environmental Impact

Electricity produced by the plant is designated as renewable energy and the plant effectively produces no net greenhouse emissions.
